My *biggest* concern is the $795 'commitment fee'.  

Their leads are Absoloutely horrible I received 90% of the letters back from mailers the script is horrible and after they get your money , their excellent mentors or cpaches disapper they are the biggest scammers out there.

I would also say that markets like Manhattan are not super representative of most markets in the US - a lot of foreign investment I'd imagine in NYC, Miami etc - I'd guess a lot of these cash purchases are more about exchanging unstable or risky foreign assets/currencies for perceived stability/safety of US top metro residential real estateI think in a lot of other markets where this isn't relevant - I think most are cash offers being "king" as not having appraisal or other contingencies that might sabotage the sale after 30 days or so and make people re-list (sellers will take less to avoid this risk and downside)

The only downside to my condo is that it is situated on the backside of the condominium it occupies and does not have an ocean view, however being aware of that I have dropped the price on significantly on the property. 

However, downsides include regulatory restrictions on bank lending, many institutions that restrict concentration and geographies, and other headaches and issues that arise when dealing with a slower-moving bank.DSCR loans are the option that has completely changed the BRRRR lending landscape in the last few years.

I see very little downside in going all in on this strategy.

The biggest impact will be interior paint, trim and doors, upgraded fixtures, bathrooms and kitchens.

I think #2 is going to be the biggest issue here.
